Leather Jackets - Underpowered

Cloth robes are in a great place right now. Cleric, Mage, Druid all serving certain roles and being used.

Leather Jackets have undergone various nerfs in the past. A few being:

Inferno Shield

Reflected Damage: 50% -> 30%

Armor Increase: 0.30 -> 0.25

With the introduction of Mage Robe's "Purging Shield" into the game, and other purge based items and weapons, leather jackets are left pretty underpowered and easily counterable. Every leather chest's unique skill can be purged. Inferno Shield, Electric Field, Bloodlust, Life Steal Aura, Haste?

Any plans to revert some of these nerfs, specifically to the Inferno Shield across the leather jacket line? These nerfs are from mid to late 2017.

Is there a reason Inferno Shield can't reflect 50% of incoming damage, or have it's armor increased by another .05?
